SPECIFICATION forming part of Letters Patent N0. 763,678, dated June 28, 1904.

Application filed February 10, 1904. Serial No. 192,930. (No model.)

To all whom it may concern:

Be it known that I, ERWIN KRAMER, a subject of the King of Prussia, Emperor of Germany, residing at No. 9 Paul street, Berlin, Germany, have invented certain new and useful Improvements in Means for Suspending Incandescent Bodies, of which the following is a specification.

My invention relates to a device for the suspension of incandescent bodies, and is intended-more especially for use with downwardlydirected or inverted burners.

The object of my invention is to provide a device for suspension in which by the provision of inclined contact-surfaces in the bayonet-joint fitting the ihcandescent-body-supporting ring is rigidly fixed, so that any oscillation is impossible, such movements being, as is well known, liable to fracture the mantle or the like. Owing to the simple form of the bayonet-joint fitting which is employed, the cost of production of the suspension device is very small, while at the same time the incandescent body is properly centered.

A further object of my invention is to arrange between the mantle-ring and the burnertube or the collar fixed thereon a packing-ring of suitable materialsuch as asbestos, for exa1nplethereby forcing the combustion-gases to pass through the mantle and not to escape along the burner-tube or elsewhere without serving for heating the incandescent body. The form of this packing-ring is immaterial. It may either be cylindrical or be conical.

In the accompanying drawings, forming part of this specification, Figure 1 is a vertical sectional view of the device and of the lower part of the bu rner-tube. Fig. 2 is a plan view of the plate fastened to the burner. Fig. 3 is a plan view of the ring which carries the mantle. Fig. 4: is a side elevation of the ring shownin Fig. 8. Fig. 5 is a vertical sectional View of a modified form of the device shown in Fig. 1. Fig. 6 is a plan view of the conical plate fastened to the burner shown in Fig. 5. Fig. 7 is a side elevation of the plate shown in Fig. 6. Fig. 8 is a plan view of a conical ring which carries the mantle.

The burner-tube a carries at its lower end a plate 7), which, if desired, may be provided with outlet-apertures for the waste gases. A ring 0, carrying the mantle q, is detachably connected with this plate. The ring or collar c is provided in two or more places with oblique cuts in its upper cylindrical portion, so that the-portionsf and f Figs. 1 and 3, lying above these cuts may be pressed inwardly. The circular plate 6, on the other hand, is formed in two or more places with flats d and (Z Fig. 2.

1n placing the collar 0 in position it is passed over the plate 6 in such a manner that the parts d and d coincide with f" and f The flange it then bears against the under face of the plate 7) and can now be rotated around the vertical axis of the burner to such an extent that f and f engage above the round portion of the plate 6. The collar 0 is thereby fixed on the plate 6, owing to the fact that the projections f and f present an inclined edge toward the side of the plate 6, which edge cannot be completely pushed over the flat portions (Z and (Z Fig. 4.

A packing-ring u may be placed on the flange 7b and bear against the under face of the plate bwhen the device is fixed on the latter, as above stated.

The form of the device illustrated in Figs. 5 to 8 is based on the same principle; but in this case the inclined faces 7c and k are arranged on the part 6, while the ring a is formed with two claws f and f beneath which the faces is and engage.

It is immaterial for the present invention how many inwardly-bent parts f and f and corresponding recesses or flats on the plate 6 are provided and whether the recesses, projections, or the like are arranged radially or axially. It is also immaterial whether the inclined faces which fix the plate to the ring or the ring to the plate are arranged on the ring (Fig. 4, f and f or upon the plate, 7, 7c and 762.) I

Combinations of all kinds may be effected between the arrangements shown in Figs. 1 to 4 and 5 to 8, respectively. The bent or bulged portionsfor example, f and f may also be directed outward instead of inward, while the plate I) will of course be correspondingly formed.

The plate 7) instead of being made flat may be provided with obliquely-bent edges for the purpose of constituting the locking-faces.

The essential feature is that by means of a bayonet-joint-like fitting formed by the parts 7) and a and provided with obliquely-arranged locking-faces of any suitable kind the ring and plate are securely fastened together. I therefore do not wish to be limited to the constructional forms illustrated in the drawings; but

That I claim as my invention, and desire to secure by Letters Patent, is

1. In a device for fastening incandescent bodies to the burner, the combination with a plate fastened to the burner-tube, of a ring carrying the mantle; two or more projections on one of said members with oblique edges, which edges engage portions on the other member; and a flange on the ring, which flange bears against the plate, and claws on the one member adapted to engage said oblique edges, substantially as described.

2. In a device for fastening incandescent bodies to the burner, the combination with a plate fastened to the burner-tube, of a ring carrying the mantle; two or more projections on one member with oblique edges, which edges engage portions on the other member; a flange on the ring, which flange bears against the plate; and a packing-ring arranged between the flange and the plate, substantially as described.

3. In a device for fastening incandescent bodies to the burner, the combination with a plate fastened to the burner-tube, the said plate having upwardly-directed projections with oblique edges; of a ring carrying the mantle; and inwardly-directed claws on the ring adapted to engage with the oblique faces, substantially as described.

4. In a device for fastening incandescent bodies to the burner, the combination with a plate fastened to the burner-tube, the said plate having upwardly-directed projections with oblique edges; of a ring carrying the mantle; inwardly-directed claws on the ring adapted to engage with the oblique faces; and apackingq'ing arranged between the plate and the ring, substantially as described.

5. In a device for fastening incandescent bodies to the burner, the combination With a plate fastened to the burner-tube, the said plate having a conical flange; of oblique projections on the plate; a ring carrying the mantle; claws on the ring adapted to engage above the oblique faces; and a conical flange on the ring bearing against the under face of the flange of the plate, substantially as described.

In witness whereof I have hereunto signed my name, this 19th day of January, 1904, in the presence of two subscribing witnesses.

ERIVIN KRAMER.
